Ofufuza apanga njira yobwezeretsanso zinthu zomwe zingathe kubweza 100% ya aluminiyamu ndi 98% ya lithiamu m'mabatire amagetsi a magalimoto.
Ofufuza aku Sweden akuti apanga njira yatsopano komanso yothandiza kwambiri yobwezeretsanso mabatire amagetsi a magalimoto.
"Popeza njira iyi ikhoza kukulitsidwa, tikukhulupirira kuti idzagwiritsidwa ntchito m'mafakitale m'zaka zikubwerazi," anatero mtsogoleri wa kafukufukuyu Martina Petranikova.
Mu hydrometallurgy yachikhalidwe, zitsulo zonse zomwe zili m'mabatire amagetsi zimasungunuka mu ma acid osapangidwa.
"Zodetsa" monga aluminiyamu ndi mkuwa zimachotsedwa ndipo zitsulo zamtengo wapatali monga cobalt, nickel, manganese ndi lithiamu zimapezedwanso.
Ngakhale kuti kuchuluka kwa aluminiyamu ndi mkuwa wotsala ndi kochepa, kumafuna njira zingapo zoyeretsera, ndipo gawo lililonse mu ndondomekoyi lingathe kutayika kwa lithiamu.
Ofufuza ku Chalmers University of Technology ku Sweden apanga njira yobwezeretsanso zinthu zomwe zingathe kubweza 100% ya aluminiyamu ndi 98% ya lithiamu m'mabatire amagetsi a magalimoto.
Zimaphatikizapo kusintha njira zomwe zikuchitika panopa komanso makamaka kukonza lithiamu ndi aluminiyamu.
Nthawi yomweyo, kutayika kwa zinthu zamtengo wapatali monga nickel, cobalt ndi manganese kumachepa.
"Mpaka pano, palibe amene wapeza njira zoyenera zogwiritsira ntchito oxalic acid kulekanitsa lithiamu yambiri chonchi pamene akuchotsa aluminiyamu yonse nthawi imodzi," anatero Leah Rouquette, wophunzira womaliza maphunziro ake mu Dipatimenti ya Chemistry and Chemical Engineering ku Chalmers University of Technology.
"Popeza mabatire onse ali ndi aluminiyamu, tiyenera kutha kuwachotsa popanda kutaya zitsulo zina."
Mu labotale yawo yobwezeretsanso mabatire, Rouquette ndi mtsogoleri wa kafukufuku Petranikova anaika mabatire a magalimoto ogwiritsidwa ntchito ndi zinthu zomwe anaphwanyika m'malo osungiramo utsi.
Ufa wakuda wophwanyidwa bwino umasungunuka mu madzi owoneka bwino otchedwa oxalic acid, chinthu chobiriwira chomwe chimapezeka mu zomera monga rhubarb ndi sipinachi.
Ikani ufa ndi madzi mu makina ofanana ndi blender ya kukhitchini. Apa, aluminiyamu ndi lithiamu mu batire zimasungunuka mu oxalic acid, zomwe zimasiya zitsulo zotsalazo mu mawonekedwe olimba.
Gawo lomaliza la ndondomekoyi ndikulekanitsa zitsulozi kuti mutulutse lithiamu, yomwe ingagwiritsidwe ntchito kupanga mabatire atsopano.
"Popeza zitsulozi zili ndi makhalidwe osiyana kwambiri, sitikuganiza kuti zidzakhala zovuta kuzilekanitsa. Njira yathu ndi njira yatsopano yodalirika yobwezeretsanso mabatire yomwe ndiyofunika kuifufuza mozama," adatero Rouquette.
Gulu lofufuza la Petranikova lakhala likuchita kafukufuku wamakono wokhudza kubwezeretsanso zitsulo m'mabatire a lithiamu-ion.
Amagwira ntchito zosiyanasiyana zogwirira ntchito limodzi ndi makampani omwe akugwira ntchito yobwezeretsanso mabatire amagetsi. Gululi ndi lothandizana nawo mu ntchito zazikulu zofufuza ndi chitukuko ndipo mitundu yake ikuphatikizapo Volvo ndi Northvolt.
